Nibiru is said to orbit the Sun every 3,600 years on a journey, which takes it beyond the fringes of the solar system. No official observations of the planet, sometimes dubbed Planet X or Wormwood, have ever been made but conspiracy theorists believe it is real. Nibiru’s passage through the solar system is said to herald the apocalypse and destruction of civilisation. The planet, which is believed to be 10 times the size of Earth, will supposedly crush our home world with its gravitational waves, triggering earthquakes, volcanoes and tsunamis.

And if these bizarre pictures taken over the US state of Wyoming are to be believed, then the doomsday planet may have already arrived over Earth.

Joshua Weickum of Casper, Wyoming, claims to have taken pictures of Nibiru high in the sky on a bright sunny day.

Mr Weickum told Express.co.uk he saw a “blue planet-like” object after snapping some photos of clouds.

He was adamant the supposed Nibiru sighting was not a lens flare on his camera but the real deal.

There is, however, no scientific evidence to support the claim Nibiru or any other doomsday planets are real.

According to US space agency NASA, all claims of Nibiru being real are a hoax.

NASA wrote on its website: “The planet in question, Nibiru, doesn’t exist, so there will be no collision.

“The story of Nibiru has been around for years (as has the ‘days of darkness’ tale) and is periodically recycled into new apocalyptic fables.”

And NASA’s scientist Dr David Morrison also said: “There is no credible evidence whatever for the existence of Nibiru.

“There are no pictures, no tracking, no astronomical observations.

“I can quite specifically say how we know Planet X or Nibiru does not exist and does not threaten the Earth.

“Firstly, if there was a planet headed into the inner solar system that was going to come close to the Earth, it would already be inside the orbit of Mars, it would be bright, it would be easily visible to the naked eye – if it was up there it would be easy to see it, all of us could see it.”
